What could take down MH17?

U.S. officials believe the plane was "likely downed by a surface-to-air missile ... operated from a separatist-held location in eastern Ukraine," the U.S. ambassador to the United Nations, Samantha Power, told an emergency session of the U.N. Security Council. It is not clear what kind of missile was used to shoot it down.

The altitude of the plane -- above 30,000 feet -- at the time of its disapperance from radar means the missile must have come from a sophisticated system.

According to experts, the Buk missile system -- known as SA-11 among NATO forces -- is one weapon that could shoot down a jet flying at that altitude. The missile system, detailed in this graphic, was developed during the Soviet era and operated by Russian and Ukrainian forces. Other possibilities include Russian-made S-200 missiles that are operated by the Ukrainian military as well as the Russian S-300 and S-400 missiles.
